In order to register the module so you can import it, you need to include it in you SystemJS configuration.
System.config({
packages: {
...
"socket.io-client": {"defaultExtension": "js"}
},
map: {
"socket.io-client": "https://stackoverflow.com/questions/37090031/node_modules/socket.io-client/socket.io.js"
}
});
And change your import to:
import io from 'socket.io-client';
import * as io from "socket.io-client
Also, you don’t need the import in the script tag anymore, so remove:
<script src="https://stackoverflow.com/questions/37090031/node_modules/socket.io-client/socket.io.js"></script>
Finally, if you like to add the typings, add in your typings.json
:
{
"ambientDependencies": {
...
"socket-io-client":"github:DefinitelyTyped/DefinitelyTyped/socket.io-client/socket.io-client.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd"
}
}
P.S. Int the future, change the hash in the typings to the latest commit hash.
